通过利用综合物探方法寻找和勘查许昌泉店大型沉积变质矿床实例的研究，认为航、地磁异常重合是一个找矿的前提；高磁测量解释为薄板状体者对应单层矿，多层叠加板状体者对应多层矿；模型体与主矿体在位置、层数、规模、产状存在较好的对应关系，而与其他小矿体在位置上有偏移，其模型体往往在矿体的下方；矿体与矿化体上均有二次导数异常。
通過利用綜閤物探方法尋找和勘查許昌泉店大型沉積變質礦床實例的研究，認為航、地磁異常重閤是一箇找礦的前提；高磁測量解釋為薄闆狀體者對應單層礦，多層疊加闆狀體者對應多層礦；模型體與主礦體在位置、層數、規模、產狀存在較好的對應關繫，而與其他小礦體在位置上有偏移，其模型體往往在礦體的下方；礦體與礦化體上均有二次導數異常。

Quandian large sedimentary metamorphic ore deposit was found by using comprehensive geophysical methods. after researching the exploration of the deposit, we conclude that aeromagnetic and geomagnetic anomalies are precondition for prospecting;high magnetic survey shows that laminated plate is single layer ore, and multilayer superposition plate is multi-layer ore;model body and the main ore bodies have a good corresponding relationship on their position, layer number, scale and occurrence, while the other small ore bodies are different in position, whose models are often found in the bottom of the ore body;both the ore bodies and mineralized bodies contain the second derivative anomaly.
